With just a little practice, you learn to change your "cheek weld" to a "chin weld"With respect to lever guns with scopes on them (or any gun stocked for low irons that has been equipped with a scope!), is not just accuracy, but speed of target aquisition: without a good, repeatable cheek weld, you'll be moving your head around trying to see the target centered through the scope while simultaneously moving the gun around to put it on target.
Too complicated for any accuracy at speed. You should be looking throught the scope when you shoulder the gun.
It's all a matter of handling your set up enough to learn what it takes
You're only talking about fractions of an inch
I have no trouble making fast shots with a Marlin 1894S with a Leu 2 X 7, although as I said in another thread, when you learn how to hunt, you don't have to take "snap shots".
